(1-2) Using a tuning fork, the resonance pattern shown is produced in a glass tube which is closed off at one end. The total length L of the tube is 100 cm from the closed end to the open end. 1. If the speed of sound is 343 m/s, the frequency of the tuning fork must be about Group of answer choices a. 320 Hz b. 343 Hz c. 429 Hz d. 858 Hz
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.

1. If the speed of sound is 343 m/s, the frequency of the tuning fork must be about
2. If the temperature of the air in the tube was increased by 10 Co, what would occur?
a. The speed of sound in the tube would increase.
b. The frequency of the sound in the tube would increase.
